Confidentiality
Results are less bias

# data[].attributes.body
allows results to be generalized

# data[].attributes.body
Participants need to remain anonymous. Results are less biased.

# data[].attributes.body
It is a better representation of the real world community

# data[].attributes.body
To provide fair and unbiased results for the chosen experiment

# data[].attributes.body
Increases probability of establishing cause and effect

# data[].attributes.body
So that the chances of establishing cause and effect is much higher

# data[].attributes.body
One of the base requirement for a true experiment

# data[].attributes.headline
It helps to give a better selection of participants

# data[].attributes.subject
It helps to give a better selection of participants

# data[].attributes.body
to compare

# data[].attributes.body
To give an unaltered base of analysis for the experimental data collected

# data[].attributes.headline
you need to compare and contrast results between the groups

# data[].attributes.subject
you need to compare and contrast results between the groups

# data[].attributes.body
There is something to compare

# data[].attributes.body
its something solid to compare your results to.

# data[].attributes.body
It helps to prevent experimenter bias

# data[].attributes.body
Some experiments cannot be randomized as experiments are done with specific groups eg those with diabetes or anxiety

# data[].attributes.body
yeah exactly

# data[].attributes.body
They provide a uninfluenced comparison to the experimenter

# data[].attributes.body
performing a quasi experiment

maybe you need to not become a psychologist

# data[].attributes.subject
maybe you need to not become a psychologist

# data[].attributes.body
you dont need them

# data[].attributes.body
some experiments dont require randomization.

# data[].attributes.body
They allow the researcher to have greater control of the independent variables allowing for better quantitative data

# data[].attributes.headline
You don't have extra factors that will affect your results

# data[].attributes.subject
You don't have extra factors that will affect your results

# data[].attributes.body
if you're looking for results from a specific group of people

# data[].attributes.body
when you are focusing on a certain group.

# data[].attributes.body
you don't need a group to compare results with

# data[].attributes.body
Then there is not a true representation of real world .

# data[].attributes.body
when performing naturalistic observation

# data[].attributes.body
deal with it
